On Board Diagnostics

[miner999r]

Hi, I have a 13 GT.
Can someone point me to a place that has the details of the on board diagnostics. Example:
Key on, engine off, press accelerator to floor to reset the ECM and start engine while holding the OK button on the steering wheel provides information on the screen between speedo and tach, but the info is coded.

Thanks
